  FIG. 8 is a perspective view showing how the conventional rod holder is used.

  The main body 5 is fastened to the anchor 4 via a mounting screw 9. That is, the mounting screw 9 passes through the main body 5 and is screwed into the anchor 4. Positioning pins 5 a are projected from the lower surface of the main body 5, and a plurality of positioning holes 4 a are provided in the anchor 4. Each positioning hole 4a is arranged on an arc centered on the mounting screw 9, and the positioning pin 5a is fitted in one of the positioning holes 4a. When the attachment screw 9 is tightened, the main body 5 is fastened and fixed to the anchor 4. When the fisherman operates the mounting screw 9 to release the fastening of the main body 5 and release the fitting between the positioning pin 5a and the positioning hole 4a, the main body 5 rotates about the mounting screw 9 with respect to the anchor 4. can do. The fisherman can fix the main body 5 in the other direction by rotating the main body 5 and fitting the positioning pin 5a with the other positioning hole 4a and tightening the attachment screw 9 again.

  In actual fishing, the angler is often required to change the direction of the body 5 relative to the anchor 4. However, this operation is very troublesome for the fisherman because the mounting screw 9 must be rotated one by one.

  The present invention has been made under such a background, and an object of the present invention is to provide a rod holder that can be fixed to and released from an anchor with one touch.

  (1) A rod holder according to the present invention is attached to an anchor provided on a ship's rim and holds a fishing rod. The rod holder includes a base plate placed on the anchor, a first posture that is pivotally connected to the base plate via a support shaft, and protrudes from the base plate by the rotation to support the fishing rod, and the base plate A support arm that changes posture between the second postures folded to the side, a lock pin that is connected to the support shaft and extends to the anchor side through the base plate, and a pivot pin that rotates the support arm. Is provided with a cam mechanism for converting into a sliding motion in a direction crossing the support shaft.

  According to this configuration, the support arm is provided on the base plate, and the support arm is rotatable about the support shaft. When the angler rotates the support arm, the support arm is folded to the base plate side (second posture) or protrudes from the base plate (first posture). When the support arm changes to the first position, the fishing rod can be supported, and when the support arm changes to the second position, it can be stored compactly. The turning motion of the support arm is converted into a sliding motion of the support shaft via the cam mechanism. Since the lock pin is connected to the support shaft, when the support arm is rotated, the support shaft and the lock pin slide in a predetermined direction (a direction intersecting the support shaft). Since the lock pin passes through the base plate and extends to the anchor side, the lock pin comes into contact with and separates from the anchor when the lock pin slides. That is, the anchor and the base plate can be fixed or released by sliding the lock pin.

  (2) The cam mechanism is provided on the support arm, the disk cam through which the support shaft is inserted and in contact with the base plate, the cam mechanism provided on the base plate, supporting the support shaft and the above-described support shaft. And a support frame formed with a guide portion for guiding the slide in the direction.

  In this configuration, the disc cam rotates as the support arm is rotated. The disc cam is in contact with the base plate, and the distance from the contact point to the rotation center of the support arm (that is, the center of the support shaft) changes as the disc cam rotates. That is, the rotation shaft and the lock pin slide in the direction with respect to the base plate. As described above, by adopting the disc cam, the lock pin slides easily and reliably.

  (3) The disc cam is formed integrally with the support arm and provided with an insertion hole through which the support shaft is inserted, and the outer edge of the disc cam is a circle centered on the insertion hole. It is preferable to have an arc-shaped portion and a plane portion that continues two predetermined points of the arc-shaped portion.

  According to this configuration, the structure of the support arm is very simple. Moreover, the shape of the disc cam is simple, and the cam mechanism is simplified.

  According to the present invention, the angler can operate the lock pin via the cam mechanism by simply rotating the support arm, and fix or release the base plate with respect to the anchor. That is, since the angler can lock or unlock the rod holder with respect to the anchor by one-touch operation, the direction of the rod holder can be easily changed in actual fishing.

A feature of the rod holder 10 according to the present embodiment is that a cam mechanism 16 is provided. By this cam mechanism 16, the turning operation of the support arm 14 is converted into a sliding operation (sliding operation along the vertical direction 17) of the lock pin 15. The base block 12 is fixed to the vise 11 by the sliding lock pin 15 or the fixed state is released.

  3 to 5 are cross-sectional views of the rod holder 10 in use. These drawings also show the operation of the cam mechanism 16.

  As shown in FIGS. 1 to 3, the base block 12 can be made of stainless steel or other steel material, aluminum alloy, titanium alloy or other non-ferrous alloy, or resin. The base block 12 is erected on the base plate 18 placed on the upper surface 30 of the vise 11, the apron 19 and the post 20 provided at the front end portion and the rear end portion of the base plate 18, respectively, and the center portion of the base plate 18. And a support frame 21.

  The vise 11 can be made of stainless steel or other steel material, aluminum alloy, titanium alloy or other non-ferrous alloy, or resin. The shape of the vise 11 is not particularly limited, but in the present embodiment, it is formed in a C shape as shown in FIG. A hole 51 is provided in the upper surface 30 of the vise 11. The hole 51 is provided in front of the upper surface 30 (front side in the front-rear direction 32: left side in FIG. 3). The hole 51 passes through the vise 11 and has a large diameter portion and a small diameter portion as shown in FIG. A lock pin 15 described later is inserted into the hole 51. A plurality of positioning holes 56 are provided on a virtual arc centered on the hole 51. That is, the positioning holes 56 are arranged radially with the hole 51 as the center. The number of positioning holes 56 is not particularly limited.

  The front-rear direction 32 base plate 18 is formed in a flat plate shape, and is appropriately provided with a hollow portion 22 for weight reduction. However, the lightening recess 22 may be omitted. Positioning pins 55 project from the lower surface of the base plate 18. The positioning pin 55 is fitted into a positioning hole 56 provided in the upper surface 30 of the vise 11.

  The support frame 21 consists of a pair of side plates 23 and 24, and these are facing along the left-right direction. As shown in FIG. 2, the groove 26 (in the claims) is formed along the vertical direction 17 (corresponding to “the direction intersecting the support shaft” described in the claims) in the pair of side plates 23, 24. The “guide section” described) is formed. That is, the pair of grooves 26 face each other along the left-right direction 27 (direction perpendicular to the paper surface in FIG. 3). The depth of each groove 26 is set to a predetermined dimension, and the distance between the bottom surfaces 28 of the pair of grooves 26 facing each other corresponds to the length (axial dimension) of the support shaft 13. Further, the width dimension 29 of each groove 26 corresponds to the outer diameter of the support shaft 13. That is, the support shaft 13 is fitted in the pair of grooves 26 and can slide in the vertical direction 25.

  As shown in FIG. 2, the support shaft 13 is formed in a columnar shape and is typically made of stainless steel. The outer diameter of the support shaft 13 corresponds to the width dimension 29 of the groove 26 as described above. A hole 31 is provided in the center of the support shaft 13 along the vertical direction 17. A screw hole 33 is provided in the center of the support shaft 13 along the front-rear direction 32. The screw holes 33 are orthogonal to the holes 31 and communicate with each other inside the support shaft 13. A thread screw 34 described later is screwed into the screw hole 33.

  The lock pin 15 is formed in a cylindrical shape and includes a main body 35 and a flange 36. These typically consist of stainless steel. The flange 36 is screwed to the lower end of the main body 35, and can be displaced relative to the main body 35 along the longitudinal direction thereof. That is, the main body 35 and the flange 36 constitute a bolt / nut screwed structure, and the flange 36 can slide with respect to the main body 35 when the flange 36 rotates with respect to the main body 35. In order to position the flange 36, the two flanges 36 may be screwed into the main body 35 and a so-called double nut structure may be employed. However, the flange 36 may be formed integrally with the main body 35.

  The outer diameter of the main body 35 corresponds to the inner diameter of the hole 31 of the support shaft 13, and the main body 35 and the support shaft 13 are fitted at a predetermined fitting intersection. With the main body 35 inserted into the hole 31, the female screw 34 is screwed into the screw hole 33 of the support shaft 13. Thereby, the female screw 34 is pressed against the peripheral surface of the main body 35, and the main body 35 is fixed to the support shaft 13. In the present embodiment, a seat portion 37 is formed on the main body 35. As a result, the tip of the female screw 34 is stably pressed against the seat portion 37, so that the main body 35 is securely fixed to the support shaft 13. But the seat part 37 may be abbreviate | omitted.

  The lock pin 15 is a component of the cam mechanism 16 and is assembled to the base plate 18 together with the support shaft 13. This assembly procedure will be described later.

  A through hole 38 penetrating in the vertical direction 17 is provided at the center of the base plate 18. With the support shaft 13 fitted in the groove 26 of the support frame 21, the lock pin 15 hangs down and is inserted into the through hole 38. As shown in FIG. 3, in this embodiment, a sleeve 39 is fitted into the through hole 31, and the lock pin 15 passes through the through hole 38 while being supported by the sleeve 39. As will be described in detail later, when the support shaft 13 slides in the vertical direction 17 along the groove 26, the lock pin 15 also slides in the vertical direction 17 along the through hole 38 while being supported by the sleeve 39.

  As shown in FIG. 2, a pair of support arms 40 and 41 are formed at the rear end portion of the base plate 18. The post 20 is disposed between the support arms 40 and 41. The post 20 is rotatably connected to the base plate 18 via a connecting shaft 42. As a result, the post 20 can swing in the front-rear direction 32 about the connecting shaft 42 as a swing center. The post 20 has a cylindrical shape as shown in the figure, and its structure is known. Although not shown, an attachment fixed to the fishing rod side is inserted into and removed from the post 20. However, the post 20 and the attachment may be omitted.

  As shown in FIGS. 1 and 3, the support arm 14 includes a boss portion 43 and a rod seat portion 44, which are integrally formed. The material constituting the support arm 14 is preferably a resin, but a metal may be employed. The rod sheet portion 44 has a known shape and has a substantially U-shaped cross section. As a result, the fishing rod is easily placed and held.

  As shown in FIG. 2, the boss portion 43 is continuous with the rod seat portion 44 and includes a pair of flat plates 45 and 46 (corresponding to “flat plate cam” recited in the claims). The pair of flat plates 45 and 46 oppose each other at a predetermined interval along the left-right direction 27. The distance D between the outer surfaces of the flat plates 45 and 46 corresponds to the distance between the inner surfaces of the side plates 23 and 24 of the base plate 18. Therefore, the boss portion 43 is fitted inside the support frame 21 at a predetermined fitting intersection.

  An insertion hole 47 penetrating in the left-right direction 27 is formed at the center of the flat plates 45 and 46. The inner diameter of the insertion hole 47 corresponds to the outer diameter of the support shaft 13, and the support shaft 13 is fitted with the flat plates 45 and 46 at a predetermined fitting intersection. The outer edges of the flat plates 45 and 46 are formed in a predetermined shape, and include an arcuate portion 48 and a flat portion 49. The arcuate portion 48 presents an arc with a predetermined radius centered on the insertion hole 47. The flat portion 49 is a flat surface that would be formed if the flat plates 45 and 46 were cut. That is, the plane part 49 presents a plane that passes through the two predetermined points on the arc-shaped part 48 and crosses the arc-shaped part 48 so as to be continuous. By forming the flat portion 49, the flat plates 45 and 46 constitute a flat plate cam as a mechanical element.

  The support shaft 13, the lock pin 15, and the support arm 14 are assembled to the base block 12 in the following manner.

  The support shaft 13 is fitted into the boss portion 43 of the support arm 14. That is, the support shaft 13 is inserted into the insertion hole 47 from the outside of the flat plate 45 or the flat plate 46 along the left-right direction 27. Since the length of the support shaft 13 corresponds to the distance between the bottom surfaces 28 of the grooves 26 provided in the support frame 21, it is larger than the distance D between the outer surfaces of the flat plates 45 and 46. Therefore, both end portions of the support shaft 13 protrude outward from the flat plates 45 and 46.

  In this state, the support shaft 13 and the support arm 14 are fitted to the support frame 21. Specifically, the flat plates 45 and 46 are inserted between the side plates 23 and 24, and both end portions of the support shaft 13 are fitted into the grooves 26. As the support shaft 13 slides downward along the groove 26, the flat plates 45 and 46 of the support arm 14 come into contact with the upper surface 50 of the base plate 18.

  As shown in FIGS. 2 and 3, the lock pin 15 is inserted into the support shaft 13 from below the base plate 18. That is, the main body 35 of the lock pin 15 is inserted into the through hole 38 from the lower surface side of the base plate 18, penetrates the sleeve 39, and is inserted into the hole 31 of the support shaft 13. At this time, the flange 36 is screwed into the main body 35 and positioned at a predetermined position. The lock pin 15 is fixed to the support shaft 13 by the screw screw 34 being screwed into the screw hole 33 of the support shaft 13. As described above, in this embodiment, the hole 51 is formed in the vise 11 and the flange 36 of the lock pin 15 is disposed so as to hold the vise 11 from below.

  Positioning pins 55 projecting from the base plate 18 engage with the vise 11. Specifically, the positioning pin 55 is fitted into one of the positioning holes 56 provided in the vise 11. As described above, since the positioning holes 56 are arranged radially with the hole 51 as the center, the orientation of the rod holder 10 (support arm) depends on which positioning hole 56 the positioning pin 55 is fitted to. 14 orientation) is determined.

  Thus, the support shaft 13, the lock pin 15, and the support arm 14 are assembled to the base block 12, so that the support arm 14 can be rotated as shown in FIGS. 3 to 5. The support frame 21 that supports the flat plates 45 and 46 of the support arm 14 and the support shaft 13 so as to be slidable in the vertical direction 17 converts the rotation of the support arm 14 into a sliding motion of the lock pin 15 in the vertical direction 17. The cam mechanism 16 is configured.

  When the support arm 14 is in the posture shown in FIG. 3 (corresponding to the “first posture” described in the claims), the support arm 14 protrudes forward from the base plate 18 and easily holds the fishing rod. be able to. Further, the support arm 14 is movable around the support shaft 13 from the first posture and passes through the posture shown in FIG. 4 to the posture shown in FIG. 5 (corresponding to the “second posture” described in the claims). Can change. When the support arm 14 changes to the second posture, the support arm 14 is folded to the base plate 18 side and stored compactly.

  A posture pin 52 is provided on the base plate 18. The posture pin 52 is erected in front of the base plate 18 and is screwed into the base plate 18. The support arm 14 comes into contact with the head of the posture pin 52 when the support arm 14 changes to the first posture. Therefore, the standing angle of the support arm 14 in the first posture is adjusted by adjusting the screwing amount of the posture pin 52. Note that the posture pin 52 may be omitted.

  When the support arm 14 is in the first posture (see FIG. 3), the arc-shaped portion 48 of the boss portion 43 (the flat plates 45 and 46) is in contact with the upper surface 50 of the base plate 18. In this state, the support shaft 13 and the lock pin 15 are pulled upward, and the vise 11 and the base plate 18 are pressed against each other by the flange 36. Since the positioning pin 55 is fitted in the positioning hole 56, the rod holder. Ten orientations are fixed. Therefore, the rod holder 10 is fixed to the vise 11.

  When the support arm 18 is rotated from the first posture to the second posture side, the intermediate posture is brought about as shown in FIG. That is, the flat portion 49 of the boss portion 43 abuts on the upper surface 50 of the base plate 18. In this state, the support shaft 13 and the lock pin 15 move downward, and the fastening between the vise 11 and the base plate 18 is released by the flange 36. That is, the rod holder 10 is released from the vise 11. As a result, the rod holder 10 can swing in the left-right direction 27 (along the direction indicated by the reference numeral 53 in FIG. 1) about the lock pin 15, and the positioning pin 55 is connected to the other positioning holes 56. Can be fitted. When the positioning hole 56 fitted to the positioning pin 55 is changed, the direction of the rod holder 10 is changed.

  Thus, the rod holder 10 is fixed only by the operation of the support arm 18 or can be rotated in the direction desired by the angler. Therefore, when it is necessary for the angler to change the orientation of the rod holder 10 in actual fishing, it has been conventionally necessary to operate the mounting screw one by one. However, in the rod holder 10 according to the present embodiment, it is easy to perform by one-touch operation. In addition, the attitude or orientation of the rod holder 10 relative to the vise 11 can be adjusted. In addition, when the orientation of the rod holder 10 is changed, the angler can re-fix the rod holder 10 in the orientation only by performing an operation of returning the support arm 18 to the first posture again.

  In the present embodiment, the base plate 18 and the vise 11 can be fixed and released by the disc cams (flat plates 45 and 46) and the lock pin 15, so that the structure is very simple and reliable. In addition, since the flat plates 45 and 46 include only the arc-shaped portion 48 and the flat surface portion 49, the cam operation is simple, and there is an advantage that the cam mechanism 16 is configured at low cost.

  In the present embodiment, the flat plates 45 and 46 include only the arc-shaped portion 48 and the flat portion 49, but are not limited to such shapes. For example, when the outer edges of the flat plates 45 and 46 have a predetermined curved surface or other shapes, the sliding operation of the lock pin 15 is controlled, and the base plate 18 and the vise 11 can be more firmly fixed. In any case, for the angler, the rod holder 10 can be fixed and released by one-touch operation of the support arm 14.

  In the present embodiment, as shown in FIG. 3, the flange 36 of the lock pin 15 has a vise 11 from below, but the engagement structure between the vise 11 and the lock pin 15 is not particularly limited. Instead, various other engagement structures can be employed. In short, any structure may be used as long as the base plate 18 is fixed to the vise 11 by the sliding operation of the lock pin 15 or the fixing is released.
